Nev: Investment finally paying off

Spurs beat Manchester City to reach the semi-finals for the first time in the Champions League era

Speaking on Renault Super Sunday, Gary Neville praised the performances of the Premier League clubs in this season's European competitions.

"We're sort of ridiculing the clubs trying to get into the top four in the Premier League but if you look at it, Tottenham are in a Champions League semi-final and Arsenal and Chelsea are in the semi-finals of the Europa League.

Up first, Tottenham vs Ajax...

Spurs team news

Tottenham were handed a big boost ahead of their clash with Ajax with the return to training of Moussa Sissoko. The France midfielder has missed the last three games due to a groin problem, but trained on Monday.

Defender Jan Vertonghen was rested during Tottenham's 1-0 loss to West Ham on Saturday but he was also in action during the training session.

Poch 'living his dream'

Mauricio Pochettino is "living his dream" by taking Tottenham to the Champions League semi-finals, but is still thinking even bigger.

Spurs host Ajax in Tuesday's first leg having reached the last four of this competition for the first time in the Champions League era.

Tottenham boss Mauricio Pochettino reveals the ambitions he set out with Daniel Levy five years ago, when the club's chairman was 'still in his pyjamas'

Tottenham boss Mauricio Pochettino reveals the ambitions he set out with Daniel Levy five years ago, when the club's chairman was 'still in his pyjamas'

"I am living my dream, I am already living it - to be in the semi-final with Tottenham," Pochettino said. "It was a dream five years ago and we are living it. Always you must dream with the moon, if you want to get something from the sky. You need to set your dreams to infinity and beyond.

"When you are ambitious and want to achieve big things you need to dream. I was always a dreamer. When I was very young I dreamed in my hometown in Murphy (in Santa Fe) one day to be a football player and I achieved it.

"It was tough to achieve all that I dreamed but I believe there is power in your mind when you are determined to achieve. If you achieve things it is because you dream, when you dream you have it in your mind and then you can get it."

Spurs' Ajax quartet

There will have been a quartet of players in the Spurs dressing room who will have given an extra smile when they confirmed their last-four date with Ajax.

Christian Eriksen, Jan Vertonghen, Davinson Sanchez and Toby Alderweireld all used to play for the Amsterdam side, with the first three joining Spurs from there while the latter came via Atletico Madrid.

Moura: We will miss Son

Heung-Min Son is suspended for the Champions League semi-final first leg against Ajax

Lucas Moura is set to play a vital role for Spurs in the absence of the suspended Son and he backed his team-mates to fill the void left by the likes of the South Korea international and the injured Kane.

"Son is a very, very good player, he's very important for us. Of course we will miss him but we have other players who can do a good job and we have a very good squad."

Ten Hag dismisses Poch's 'unfair' claim

Ajax manager Ten Hag has pointed towards the television money Tottenham receive as a reason why their Premier League game at the weekend was not cancelled.

The Dutch side had their Eredivisie fixture called off to give them maximum preparation time for the Champions League semi-final on Tuesday while Spurs had to play West Ham in a London derby.

"I can't really say a lot about that", he said of Pochettino's claim. "There are always different circumstances, we get 10m (euros) from TV, they get a lot more, is that still unfair for them or for us? Everyone has different circumstances."

Merse: Difficult tie for Spurs

Speaking on The Debate, Paul Merson thinks Tottenham face a tricky night when Ajax are the visitors at the Tottenham Hotspur Stadium.

"I really fancied Spurs against Ajax, I really did," he said. "I watched Ajax and Real Madrid and Juventus gave them no respect all. Ajax caught them out and they embarrassed them in the end.

"Tottenham will show them a lot of respect but if Spurs had all their players fit and available they would've beat them. Now you look at it with the injuries and some of the players missing and it's going to be difficult. When I watched them against West Ham at the weekend it looked like a couple of the players were running in treacle."

On the other hand, Paul Dickov thinks Pochettino's side may have had one eye on the Ajax game during their defeat to West Ham.

"I fancy them over two legs in the Champions League against Ajax," Dickov said on The Debate. "I know they've got injuries and everything else, and I think the West Ham game on Saturday they possibly had one the game with Ajax this week."

Spurs' success owes much to their Dutch opponents. Adam Bate caught up with former Ajax midfielder Enoh Eyong to find out how the club shaped the development of Tottenham's key players Christian Eriksen, Toby Alderweireld and Jan Vertonghen...

Key stats

Tottenham have won both of their previous meetings with Ajax in all competitions, winning both legs in the first round of the 1981-82 Cup Winners' Cup (3-1 away, 3-0 at home).

Ajax have won just one of their six previous Champions League meetings with English opposition (3-1 vs Man City in October 2012), with all three of their away games finishing as draws (twice vs Arsenal, once vs Man City).

Charlie Nicholas' prediction

Tottenham are hitting this awkward spell at the moment. Are they the favourites? They have never been here before. Ajax, as players, have never been there before but their side have on some occasions.

This young side do not have any fear, they have five or six super young players who know how to get the job done.

Only Lionel Messi (13) has been directly involved in more Champions League goals this season than Ajax's Dusan Tadic (9 - 6 goals, 3 assists)

Dusan Tadic didn't have the consistency at Southampton but he and Daley Blind have been great. Tottenham, on their day, with the pace of Lucas Moura, alongside the skill of Christian Eriksen and Dele Alli, are guaranteed to score.

I feel Ajax will play and open up the game. Spurs could afford to let Manchester City come onto them, but they will see more possession here. I see Tottenham securing the first-leg advantage ahead of next week's return in Amsterdam.
